How about this:
Instead of the default being "No icon" when creating a thread it is
Then keep the following icons:
Cricket
Horsey (maybe could be anything about gambling)
Football (non - BHAFC)
Falmer
TV
Music
Cooking
News/Current Affairs
Chillies
Formula 1
Egg Chasing
Video Games
Other Sport
Misc
Of the current icons, the man with the hat, the lizard, the bang and the yellow box seem pointless and should go I reckon. 15 seems a good number as it would fill up both rows of the "Post Icons" box.
This is the way forward. Although not the rubbish Albion badge, the round one instead.
